If you want to talk about Emissions and how to lower emissions, there are a lot of theories on how to do that. Maybe start a different thread on that topic.
There are always exceptions to any concept.
One manufacturer got into trouble for Lean Burn strategies.
Most think lean burn is the right direction to go UNTIL YOU BLOW THE NOx EMISSIONS
which are caused by lean burn being too lean.
Companies were just trying to figure out emissions in 1970.

Most would say that a chamfer on the intake valve side is there for better flow.
Chamfers on both sides of a block would say, the engineers are doing something else in the combustion strategy.
